Whining Noise from engine

I recently dunked my taco in a good sized mud hole (depressing story...i was an idiot), the truck had water up to the bottom of the headlights and the tail was sticking out on land. It was stuck up to the frame in mud. I ended up having to replace the starter, serpentine belt, and a few idler pulleys. The only problem I still have is a whining noise coming from the engine. It happens while at any speed while I'm accelerating and also when I start the truck up. Any ideas?

 

Alternator...

 

Alternator... they don't like water.

 

I also took it to toyota to get it looked at. Thats when i had the pulleys fixed. I'm surprised they didn't say anything. Does it mean the alternator is about to go out?

 

Could be the starter pm tacowestly he had this problem his brother took his truck through a mud pit and he might know how to fix it

 

You could thereotically take the alternator out and soak the windings inIsopropyll Alcohol, and I'm not referring to rubbing alcohol either. Iso is a great electronics cleaner, evaporates quickly as well. Unless you kinda have an idea of what you're doing, I wouldn't do it yourself. You don't want to ruin the bearings. My own father tried cleaning one here a little while back and it started smoking and eventually failed in two days. God only knows what he used... LoL

 

Doesn't the starter disengage after the truck is running?

 

I have this same issue, if I replace the alternator will my truck perform any better or will it just take the noise away?

 

Im just throwing things out there haha

 

Thanks for the help guys. Just dropped it off a my mechanics to see what they think the problem is

 

Must have been one of those "supercharger installation" mudholes.

 

Did this mud hole install a super charger on your Taco?

Use denatured alcohol for electronics exclusively.

 

Mechanic said it was the alternator. This was some seriously expensive offroading.
